With recent news of heat and wildfire in the Pacific Northwest, I'd looked using the Nullschool Earth weather visualiser for similar signs elsewhere. The submitted article is one of the few mentions of this year's Siberian forest fires I can find. (The fires have become something of an annual occurrence.)

The Yakutia region of Siberia is under a staggering amount of wildfire. The fires seem to have been burning since May, though by both particulate and CO channels at Nullschool, have exploded in size and intensity in just the past 48 hours or so (that would be after the dateline of this article).

Several videos on the article show conditions on the ground.

I'm linking two snapshots of current conditions as noted by Nullschool, showing smoke and more specific combustion channels.

Particulate channel, shows the location generally of smoke. I’ve selected the PM1 rather than PM2.5 channel as the latter is somewhat noisier, though it’s generally what’s used for smoke tracking. Both are fine particulate matter.

CO channel, where carbon monoxide is a much more specific indication of where there is current combustion. These signal regions themselves are immense. My eyeball estimate is that the fires cover a region roughly the size of the state of Oregon.

It's possible to select SO2 and NO2 channels as well, both of which also tend to indicate current combustion, though with specificity intermediate between CO and PM1.
